` 4' (c1. zoe-44)' Generally deined, an object of my present irl-- venton is to provide ani improved wrapper for l l commodities such as pies, which is simple in construction and extremely effective in use. In my prior PatentNo. 2,005,208, granted June 18, 1935, I have shown an improved wrapper for pastries, such as a. pie resting in a relatively l5 rigid pie plate having a resilient rim, the wrapping comprising a transparent sheet of thin flexible material covering the pie extending downwardly beyond. the peripheral rim of `the supporting plate, and an endless flexible polygonal band member encircling the plate and having therein a series of elongated slots for receiving successive portions of the plate rim and for folding the covering sheet about these rim portions.

While this prior Wrapper when once properly applied, is extremely effective and commercially satisfactory, the spring action of the plate rim which is relied upon to produce clamping as the band member is lowered vertically over the covering sheet and the rim of the' plate, makes it rather diilicult toapply the clamping band to the assemblage and sometimes causes the bands t burst. I have found that this spring actionof the' platev rim can be practically obviated, by

properly forming the retainer band, and that the wrapping structures may also be more readily assembled without breaking the bands and without distributing-'the position of the covering sheet relative to the enwrapped article.

It is therefore a more specic object of my 40 present invention to provide an improved clamp'- ing band for wrapping assemblages of the above described type, which may be conveniently applied and which will effectively retain the wrapper in assembled condition.

Another specific object of my present invention is the provision of a new and useful commodity wrapper which is adapted for use in wrapping any relatively ilat and generally circular article resting upon a relatively rigid support, so that the article will be eectively protected and concealed but will still be visible to prospective purchasers.

A further specie object of this invention is to provide an improved wrapper having an improved assembly band of the continuous and locally slotted type formed so that the article itself will These and other objects and advantages of my X0.

present invention will be apparent from the following detailed description, and some of the novel Afeatures of wrapper construction shown but notspecifically claimed herein, form the subject of niv said prior patent.

A clear conception of several embodiments of my present improvement, and ofthe mode of constructing and of utilizing commodity wrappers made in accordance with this invention, may be had by referring to the drawings accompanying and forming a part of this specification, wherein like reference characters designatethesame or Similar parts in the various views.

Although I Vhave shown my improved wrapper as having been applied to only two specific kinds of substantially circular commodity, it is not in- -`-.tended to thereby unnecessarily restrict the scope,

I[since some of the improved features may obviously be advantageously applied in wrappings for other objects having different shapes than those illustrated.

Referring especially to Figs. 1 to 5' inclusive, the improved piewrapper illustrated therein, comprises in general a relatively stiff support such as a standard paper pie plate I5 for normally confining and supporting the pie I6; a thin flexible sheet I1 of cellulose film or other relatively transparent material disposed over the top of the pie I6 and depending over the peripheral edge or rim I8 of the plate I5; and a continuous sub` stantially polygonal clamping band I3 having a v outwardly beyond the peripheraledge of the pie I6 in order to permit proper application ofthe other elements of the wrapper.

The covering or enclosure sheet I1 is preferably formed of some tenacious and relatively transparent material in order to make the enwrapped object clearly visible therethrough, and when the pie I6 or other object which is to be enwrapped, is substantially circular, the sheet I1 would also be of substantially circular shape and of sufticient diameter to overlap the rim I3 to a considerable extent. 1

The improved clamping band I3, besides being continuous and provided with the slots 2li, is preff erably polygonal in form before and after being applied to the assemblage, but is distortable into substantially circular shape havingan internal diameter slightlygreater than that of the plate rim I3, during application thereof to the packaage. Theband I3 may be formed from a strip of relativelyheavy but easily distortable material such ascard board, and the strip is provided with local scoring 2I and has its ends 22 permanently connected by stapling or gluing to produce the polygon which in the present disclosure is an octagon. In accordance with my improvement, the strip or band I9 is also provided with -a series of notches 23 located one at the lovverv end of each scoring 2l, and is also provided with scoring 24 connecting the upper ends of the successive notches 23 so as to provide an outwardly bendable` `tongue or flap 25 at the lower portion of each side or section of the polygon. The band- I3 may also be provided with sets of inwardly extending triangular' projections 26 adjacent the lower medial portion of each of the slots2ll, and it is to be noted that the band I 9 by virtue of the scoring 2I, 24 may be folded intorelatively fiat condition for shipment in condensed form.

When it is desired to apply one of the improved wrappers to-a plate I5 bearing a pie I5, it is preferable toflrst loosely apply the transparent covy ering sheet I1 so -that the edge portions thereof will overlap all parts of the rim I3, whereupon the retainer or clamping band I5 may be distended andlowered over the initial assemblage. The iiaps 25 upon engaging the sheet I1 at the rim I 3 will automatically swing outwardly about the horizontal scorings 24 and the medial portions of the band sections directly above the scorings 24 will bend outwardly to permit relatively unobstructed lowering of the band I3 until the adjacent portions of the rim I8 enter the slots 2li. The sections of the band I3 between the vertical scorings 2I will thereafter tend to straighten and will thus cause the resilient projections 26 and the adjacent walls of the slots 2li to engage the portions of the sheet I1 coacting with the bottom of the rim I3, as clearly shown at the right of Fig. 2. The straightening of these band sections will also simultaneously cause the scorings 2l to spread away from the rim I3, thus permitting the adjacent portions of the covering sheet I1 to move away from the rim and to produce small vent openings 21 as shown at the left of Fig. 2. During application of the band I3. the flaps 25 prevent shifting of the covering sheet I1 relative to the pie I6, and the wrapper when thus finally assembled, effectively conceals and protects the pie I6, while the openings 21 provide sufficient venting to prevent the commodity from becoming rancid. Thewrapper may obviously be readily removed by merely tearing the band I9 and by thereafter removing the covering sheet I1.l

Referring more particularly to the modified embodiment of Figs. 6 to 10" inclusive, the improved chocolate-nut bar wrapper illustrated ltherein, comprises in general a relatively stiff support such as a flat dish or plate 30 for normally supporting the bar 3 I; a thin flexible sheet 32 of relatively transparent material disposed `over the top of the bar 3| and extending downwardly beyond the rim or edge 33 of the plate 3i);y and a substantially polygonal and continuous clamping band 34 having a series of elongated slots 35 therein for receiving local peripheral portions of the plate edge 33 so as to clamp the adjoining portions of the covering sheet 32 thereagainst.

The plate 30 may be formed of card board or of any other relatively stiff material and may be round or of any other desired shape substantially corresponding to the shape of the article, but the rim edge 33 should preferably project outwardly beyond the bar 3I. The covering orv enclosing sheet 32 may be lformed of cellulose film or other relatively transparent and relatively tough material, and should be sufliciently extensive to project well below the bottom of the supporting plate 33.

The improved clamping band s4 or Figs. 6 to 10 inclusive is similar to that of Figs. 1 to iV inclusive, in that it'is continuous, polygonal in shape, and is formed of relatively heavy but easily distortable material such as cardboard. The band 34 also has spaced vertical scorings 33 and a notch 31 at the lower end of eachof these scorings, and is provided, with horizontal scorings 33 which connect the upper ends of the notches 31 to provide laterally swingable tongues or flaps 33. The ends4ll of the band 34 are again per-l manently interconnected bystapling, gluing or otherwise, and may be collapsed into relatively iiat condition for shipment.

When it is desired to apply one of the modified improved wrappers toa disk or plate 33 having a chocolate nut bar 3| resting thereon, the transparent covering sheet 32 should rst be applied over the object and plate edge 33, whereupon the continuous clamping band 34 should b'e distended and lowered over the initial assemblage. In order to permit convenient application of the band 34, the plate 33 may be temporarily supported printed matter or the like, and to maintain this the assembling operation continues, as clearly shown at the right of Fig. '1. As soon as the edge portions of the plate 30 enter the slots 35, the portions o1' the band 34 between the vertical scorings 36 tend to straighten and thus not only maintain the band in assembled condition, but alsov produce vent openings 4I at the corners of the polygon, as shown at the left of Fig. 7. The modified wrapper when thus assembled, also effectively conceals and protects the bar 3l, and this wrapper may likewise readily be removed by tearing or pulling oil' the band 34 and thereafter removing the covering sheet-32.

I irom the foregoing description it will be ap- -parent that the present invention provides an improved wrapper for pies and the like, which may be conveniently applied and removed, and which moreover effectively encloses the commodity while at the same time properly venting the enclosure. I'he enwrapped articles may be stacked upon each other in a most eil'ective manner, and the improved construction Aof the continuous clamping bands with the lower flaps, permits rapid and ef- Iective application of these hands without danger of breakingthem. The' flaps, during application of the bands to the plates, provideeective guides ,and cause the plate edges or' rims .to quickly enter the slots while at the same time pulling the cover sheet taut; and when projections 2B are used, these also serve to maintain theband in taut clamped position. .The projections 26 are so -iormed that they are relatively springy and biased inwardly, and they will not atten into the plane of the band I9 due to collapse of this band for shipment. In some cases, itis desirable to provide the outer transparent covering sheets with printed matter in a deilnite position relltive to the nally enwrapped article. The use o! the lower ilaps coasting with the covering and with the edge portions of the article to automatically guide the band into tlnal position when the band is being ilnally applied, prevents such undesirable shifting of the outer covering and maintains the printed matter in the desired position. The improved wrapper while eilectively concealing, protecting and venting the enwrapped article,'per mits` observation thereof at all times, and the clamping bands may obviously be scored to pro-'- duce polygons of any desired number of'sides.

The present improved wrapper has proven highly successful in actual use and may obviously 'be 811-.

i plied to various kinds of commodities.

It should be understood' that it is not desired to limit the invention to the exact details of coni struction and,to the precise mode of use, herein shown deilectable flaps normally depending from the the center of each-of said slots and a pair oi' slits.
